Committed. I am also trying to figure out what should be used in the
RSB to build a current toolset:
I have a local change to upgrade to dtc 1.4.1 since the location of 1.2.0
no longer exists. That got me to the point where gcc 4.9.2 is built.
I tried the build with binutils 2.24 and binutils 2.25. What combination
binutils version do you recommend for 4.9.x gcc? I am trying to help
narrow down the options for 4.11 tools.
